Description

Http proxy service method, server and system

Technical Field

The invention relates to a proxy service method, a server and a system, in particular to an Http (hypertext transfer protocol) proxy service method, a server and a system.

Background

The existing Http proxy service mainly depends on providing a fixed IP address for a Http request party to realize proxy service of the Http request, which is not beneficial to hiding and protecting the IP address of the Http request party, and the fixed IP address has limited resources and cannot realize quick processing of the Http request.

Disclosure of Invention

The invention mainly solves the technical problems that: in the prior art, all Http proxy service outlets (IPs) are fixed IP addresses (Internet Protocol addresses), and the number of IP addresses is limited, which cannot achieve the purpose of really hiding and protecting the IP Address of the Http request party. In order to overcome the defect that the IP address of an Http request party cannot be effectively hidden and protected in the prior art, the Http proxy service method, the Http proxy server and the Http proxy service system are provided, and the IP address of the Http request and the IP address of the actual execution access are isolated by using the Http queue, so that the purpose of hiding and protecting the IP address of the Http request party is realized.

obtaining an Http request and placing the Http request into an agent request queue;

the agent request queue acquires a network outlet IP address;

the agent request queue executes the Http requests in sequence according to the queue order, and feeds back the request result to the IP address corresponding to the Http request.

In the invention, the Http queue is used for isolating the IP address of the Http request from the IP address of the actual execution access, thereby realizing the purpose of hiding and protecting the IP for initiating the Http request.

Preferably, the network egress IP address is updated periodically.

Preferably, the network outlet IP address is an ADSL (Asymmetric Digital subscriber line) IP address.

The invention also provides an Http proxy server, which is characterized by comprising the following components: the system comprises an agent request queue, a request interface, a queue message acquisition interface and a queue message write-back interface;

the request interface acquires an Http request and writes the Http request into the proxy request queue;

the queue message acquisition interface sequentially acquires Http requests from the agent request queue according to a queue sequence, and pushes and executes the Http requests through the acquired network outlet IP address;

the queue message write-back interface acquires a request result obtained by executing the Http request and feeds the request result back to the agent request queue;

and the agent request queue pushes the request result to an IP address corresponding to the Http request through the request interface.

The Http proxy server of the invention isolates the Http request party from the network for executing the actual request, thereby realizing the protection of the Http request party IP address.

Preferably, the request interface obtains the Http request through a TCP Protocol (Transmission Control Protocol); the request interface also feeds back a request result through the TCP protocol.

Preferably, the queue message acquiring interface pushes and executes an Http request through a TCP protocol; and the queue message write-back interface acquires a request result through a TCP protocol.

The invention also provides an Http proxy service system, which is characterized by comprising the following components: the system comprises a proxy server, a calling end and a request processing end;

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

In order to realize the protection of the IP address of the calling terminal and simultaneously realize the effective utilization of the dynamic IP resource of the request processing terminal, the invention realizes the random change of the IP address of the outlet while hiding and isolating the IP address of the user by isolating the IP address of the Http request from the IP address of the actual execution access and dynamically allocating the IP address of the actual access.

The present invention is further illustrated in detail by the following examples.

Example 1

As shown in fig. 1, an Http proxy service system proxy server 1, a caller 2, and a request handler 3 of this embodiment are provided, where the Http proxy service system Http proxy service method of this embodiment has the following flows:

step 1, each calling terminal 2 sends an Http request to the proxy server 1.

Step 2, the agent server 1 receives the Http request, and puts the Http request into a request queue (not shown in the figure).

And step 3, each request processing terminal 3 respectively acquires an Http request, forwards the Http request and acquires a Http request result.

And 4, the request processing terminal 3 sends the Http request result back to the proxy server terminal 1.

And 5, the proxy server 1 feeds back the Http request result to each calling terminal 2 respectively.

The number of the call terminals 2 and the request processing terminals 3 may be any number, and the number of the call terminals 2 and the request processing terminals 3 is not limited in this embodiment and the drawings thereof.

For example, for a single caller and a single request handler, the Http proxy service system works as follows:

first, the IP address of the calling terminal 2 is 1.2.3.4, and the calling terminal 2 wants to access http:// www.ctrip.com.

The calling terminal 2 sends a request which wants to access http:// www.ctrip.com to the proxy server terminal 1 through a TCP protocol.

After receiving the request, the agent server 1 puts the request content into a queue in a system memory, and waits for the request processing terminal 3 to obtain processing.

The request processing end 3 uses the ADSL network, can control the re-dialing ADSL network, after every re-dialing, the network outlet IP address will change. Assume that the IP address of the network egress after this redial is 6.7.8.9. By the method, the dynamic IP address allocation at the actual access position can be realized, and the dynamic IP resources can be more effectively utilized.

The request processing end 3 periodically redials the ADSL network, for example, after redialing, the original IP address 6.7.8.9 changes, for example, to 9.8.7.6, and changes to other IP addresses after redialing again, thereby achieving the random change of the proxy egress IP address.

The request processing terminal 3 obtains the access request (i.e. the request for accessing http:// www.ctrip.com) in the queue from the proxy server terminal 1 through the TCP protocol.

The request processing end 3 accesses http:// www.ctrip.com, and the IP address of the request received by the ctrip.com server is 6.7.8.9 instead of 1.2.3.4, so the purpose of hiding and protecting the IP address of the calling end 2 is achieved.

The request processing terminal 3 returns the result to the proxy server terminal 1 through the TCP protocol. Then the proxy server 1 feeds back the request result to the calling terminal 2 through the TCP protocol.

And the calling end 2 receives the returned content of the Http:// www.ctrip.com, the local calling is finished, and the user realizes the Http access request.

Example 2

As shown in fig. 2, the Http proxy server of this embodiment includes a proxy request queue 11, a request interface 12, a queue message obtaining interface 13, and a queue message write-back interface 14, where the request interface 12 obtains the Http request through a TCP protocol and writes the Http request into the proxy request queue 11.

Then, the queue message obtaining interface 13 sequentially obtains Http requests from the proxy request queue 11 according to the queue order, and pushes and executes the Http requests according to the TCP protocol through the obtained network egress IP address.

After the external processing unit processes the Http request, the queue message write-back interface 14 obtains a request result obtained by executing the Http request through a TCP protocol, and feeds the request result back to the agent request queue 11.

Thereafter, the proxy request queue 11 pushes the request result to the user corresponding to the IP address corresponding to the Http request according to the TCP protocol through the request interface 12.

This embodiment may also replace the proxy server in embodiment 1 to implement transmission and transfer of requests and request results between the calling end and the request processing end.
